How the clue works
Topic? is your definition, with a cheeky cryptic wink — CHOCOLATE is a "hot topic" in the literal sense, a topical treat. Then new is your anagram indicator, and sure enough if you shuffle the letters of Teach cool around, T-E-A-C-H-C-O-O-L rearranges beautifully to give you your answer.
